The Sigma 30mm f/2.8 EX DN Lens for Sony E Mount Cameras is a standard fixed focal length lens designed specifically for mirrorless interchangeable lens cameras. This 30mm lens is equivalent to a 45mm lens in 35mm format and provides a 50.7° angle of view.

Featuring a newly developed linear AF motor, this lens is ideal for use with video and still photography. The linear motor helps to guide the lens elements directly without the need for gears or other noisy mechanical parts, providing quiet and accurate focusing.

An aspherical lens design across 2 glass elements provides correction for distortion, field curvature, and color aberration while Sigma's super multi-layer coating helps to reduce ghosting and flare. With a minimum focusing distance of 11.81" (30cm), there is room for selective focus and creative depth of field applications, featuring an attractive bokeh due to the rounded 7 blade diaphragm. Sharp and high contrast results are available throughout the aperture range, even with the wide f/2.8 opening.
